VAPORIZER FOR HYDROCARBON ENGlNES.

SPEGIFIGATION for-tiring part of Letters Patent No. 695,060, dated March. 11, 1902.

Application filed May 7, 1900.

T0 (tZZ whom it may concern:

Be it known that I, AUGUST KRASTIN, a citizen of the United States, residing at Portland street, Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Hydrocarbon Explosive-Engines, of which the following is a specification.

My invention relates to improvements in hydrocarbon explosive-engines; and the objects of my improvement are, first, to provide for a suitable contrivance whereby and wherein the air and liquid fuel can be supplied in proportionate controllable quantities; second, to insure of a thorough mixture of the air with the liquid fuel; third, to provide for a mechanism whereby the air and fuel passages can be simultaneously opened and closed, also together with a relief-valve at the engine-cylinder, if so desired, and, fourth, to so construct said mechanism as to make it extremely simple and reliable in construction and convenient in point of manipulation. I attain these objects by the means and in the manner substantially as illustrated in the accompanying drawings, in which Figure 1 represents a part plan and part sectional view of an engine-cylinder and at taohment for supplying and mixing the charges therefor. Fig. 2 represents a vertical sectional elevation of the same, and Fig. 3 represents a transverse sectional View on line X X.

Like letters of reference denote like parts in the drawings and specification.

Substantially the improvement comprises the air valve or cook A, the needle-Valve B for the liquid fuel, the casing O, (combining the two first-named elements,) the levers D E, and the shifter F, the latter being connected with both of said levers. In the drawings the casingO is shown as connected in open relation with the inlet-valve cage a. G

- indicates the head, H the cylinder, and I the piston, of an explosive-engine. The exhaustvalve K is shown as seated in the cylinderface directly underneath the inlet-valve. Such or similar may be the conditions under or with which the above-mentioned improvements are applicable. The free end I) of the casing is flaring and provided with a wire netting or gauze 0. Provided in close proxsenn No. 15,737. (No model.)

imity thereto is a sleeve for the air-cock A, and farther on the needle-valve sleeve has a screw-threaded connection in and through the side of said casing. (See Figs. 1 and 3.) Theneedle-valve B is screw-threaded in said sleeve and controls the opening 6 near the inner terminal thereof. The outer terminal is preferably provided with a stuffing-box to prevent leakage past the needle-valve stem. The inner terminal of said sleeve is shown in T form extending into the path of the current, which is created upon the outward stroke of the piston. Liquid fuel is supplied to the cavity c of said sleeve by way of the branchf. (See Fig. 3.) Intermediate said branch and the feed-tank proper (not shown) there is applied some suitable vessel, as in dicated at g, for collection of impurities or other foreign substances which are oftentimes contained i n liquid fuel (hydrocarbon fluids.) It is essential that the fuel should reach the needle-valve in practically pure state, for as said valve is'nioved only slightly from off its seat, impurities would thus soon clog the valve-orifice or the diminutive passages h leading therefrom into the path of the air-current. In fact, in liquid feeds of this kind the suction action of the piston is partly depended upon for drawing the requisite quantity of liquid past the valve orifice. Clogging of the valve-orifice would thus at once interfere with the proper working of engines depending for a charge upon fuel supplied in finely-adjusted quantities. In placing the liquid fuel directly in the path of the air-current (induced by the suction action of the piston) a thorough mixture can be obtained of the charges entering the cylinder. The fuel instead of being discharged from a single point into the casing O is dis charged from both the upper and lower ends of the terminal into the center of the casing C, where the liquid is caught by the inflow ing current of air, and thus forced to commingle thoroughly therewith. The wire-netting c (gauze) at the mouth of the casing has the double function, namely, that of collecting dust and of subduing (diminishing) the noise incurred by the suction action of the piston.

To the stem of the air-cock A, as well as that of the needle-valve B, is secured a lever,

respectively as at D and E, and both the levers are connected with and by a shifting bar or rod F, whereby simultaneously the aircock and needle-valve can be turned or set, as conditions may require. Obviously the levers are connected with the air-cock and needle-valve in such manner as to assure at all times a proper mixture of air and liquid fuel. In addition to the first-mentioned aircock and needle-valve the lever of a cylinder relief-valve L may likewise be connected with said shifter, as shown in Figs. 1 and 2, the connection of which, however, must be in such a manner as to effect a closing action of said valve the moment the air and feed valve is opened, or, vice versa, such relief-valve is opened when the other valves are closed.

In starting explosive-engines it is desirable that the cylinder should be relieved of compression when the turning of the crank-shaft has to be effected by manual labor. Such relief, however, should cease the moment explosive charges are admitted to the cylinder. When the levers of the respective valves are connected to the same shaft, bar, or lever, all of them are operated simultaneously, and the air from the cylinder can be discharged through the valve L at the same moment that the other two valves are operated. Furthermore, in motor-vehicles this improvement is especially desirable, since the mechanism and manipulation of such Vehicles must be of necessity extremely simple and far-reachingthat is, by the movement of a single lever one should be enabled to practically effect the starting and stopping of the motor of such vehicles.

WVhat I claim, and desire to secure by Letters Patent, is-

1. In an explosive-engine, the cage for the inlet-Valve, the casing to said cage, an air-' valve placed in said casing, a terminal inlet for the feed of the fuel into said casing, a needle-valve for controlling said inlet; said inlet being arranged in the center of the casing and provided with a plurality of openings through which the fuel is fed, combined with arms or levers connected to the air and needle valves, the cylinder having a relief-valve in its head, an arm connected to said reliefvalve, and an operating-rod connected to the arm or lever of all three of the said valves, substantially as described.

2. In an explosive-engine, the cylinder, the piston, the inlet and outlet valves, the inletvalve cage and the casing connected to the cage of the inlet-valve and through which air is admitted, combined with the air-valve placed in the casing, a needle-valve for controlling the feed of the fuel, an inlet-terminal for the admission of the fuel into the casing, and a relief-valve upon the head of the cylinder, the levers connecting to the air, needle, and relief valve upon the head of the cylinder, and a single operating-lever by means of which all three of the last-named valves are operated simultaneously, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

AUGUST KRASTIN.
